  • Patent number: 11019774
    Abstract: The present invention is a plant cultivation device. The water tank supplies cultivation water to the cultivation tank via an irrigation conduit. The water tank also suctions cultivation water from the cultivation tank via a water-sucking pipe. The heat-collecting part receives sunlight, and the pressure of air that is heated inside the air-storage part presses the surface of the water inside the water tank. The water tank supplies cultivation water that has been pressed by the air to a culture medium material. The heat-collecting part raises the surface of the water inside the water tank as a result of the heated air being cooled by a decrease in the sunlight. The water tank suctions cultivation water from a bottom section of the cultivation tank.

  • Patent number: 7865401
    Abstract: A simple, easy, and safe electronic settlement system is provided. A user terminal such as a cellular phone is wirelessly connected to a synchronizing server. A cashier server of a mail order retailer activates a virtual cashier terminal, and connects to the synchronizing server. The synchronizing server sets a transaction identifying number in order to identify the transaction, and sends to the user terminal information about the cashier server and the transaction identifying number. A user confirms the cashier server, and returns the transaction identifying number to the synchronizing server. The synchronizing server completes a transaction between the virtual cashier terminal and the user terminal, both of which are corresponded to each other by the transaction identification number. The user can complete a settlement of mail order without telling his or her personal information such as a credit card number or a password to a mail order retailer. A security of the system is improved.

  • Publication number: 20090006144
    Abstract: A ticket use system having a high safety and a high operability and suited to be put into practical use. In the ticket use system, a strap tag storing first identification information is given to the user. When reservation of a reserved seat is made through a cellular phone, the reservation content is displayed, and a card tag storing second identification information is given to the user. The strap tag and the card tag are used as tickets. When the user registers seat type information through the cellular phone at the reservation and when the seat type information represents a nonreserved seat, the first identification information is stored as ticket authentication information in a ticket DB. When the seat type information represents a reserved seat, the second identification information is stored as ticket authentication information in the ticket DB.
